论文摘要
我们提出了在眼科应用中使用激光全息图中使用弥漫性照明的好处。整合扩散元件会在光辐射中引入角多样性并降低空间连贯性,从而有效地在目镜的整个焦平面上分布照明束的能量。这种配置允许在数字计算的视网膜图像中建立扩展的视野,因为目镜可以更靠近角膜,以实现视网膜的麦克斯韦视图而不会损害眼部安全。通过避免在角膜附近形成激光热点,弥漫性照明促进了更容易遵守美眼设备的美国和欧洲安全标准。重要的是,这种方法不会对数字计算的多普勒图像产生任何不利影响。
We present the benefits of using diffuse illumination in laser holography for ophthalmic applications. Integrating a diffusing element introduces angular diversity in the optical radiation and reduces spatial coherence, effectively distributing the illumination beam's energy across the focal plane of the eyepiece. This configuration allows for an expanded field of view in digitally computed retinal images, as the eyepiece can be positioned closer to the cornea to achieve a Maxwellian view of the retina without compromising ocular safety. By avoiding the formation of a laser hot spot near the cornea, diffuse illumination facilitates easier compliance with American and European safety standards for ophthalmic devices. Importantly, this approach does not introduce any adverse effects on digitally computed Doppler images.
